New Approaches to Drug Addiction Therapy
Nadia Halim | Sep 26, 1999 | 7 min read
Drug and alcohol addiction costs the United States more than $100 billion a year. Neither law enforcement nor therapy has been able to adequately combat this problem, so it continues to grow. Some researchers are taking a new approach: Instead of looking at addiction as lack of self-control or escape, why not see it as a chronic, reoccurring disease? Research substantiates that there are fundamental biological processes at work in the brain of a drug user. Long-term changes occur there, predisp

Drug Institute Tackles Neurology of Addiction
Karen Young Kreeger | Aug 20, 1995 | 8 min read
Tracing its origin back 60 years to the Research Division of the United States Narcotics Farm--a treatment facility for opiate addicts located in Lexington, Ky.--the National Institutes of Health's National Institute on Drug Abuse (NIDA) has grown into the world's largest drug addiction research facility. Sidebar: DISCUSSING THE SCIENCE BEHIND DRUG ADDICTION "This institute intramurally and extramurally provides 85 percent of the world support for research on drug abuse and addiction," remark
Illustration of newly discovered mechanism allowing kinesin to “walk” down a microtubule. A green kinesin molecule with an attached yellow fluorophore is shown passing through a blue laser as it rotates step by step along a red and purple microtubule, fueled by blue ATP molecules that are hydrolyzed into orange ADP and phosphate groups.

Psychoactive Drugs and Infectious Diseases
A. J. S. Rayl | Apr 16, 2000 | 10+ min read
For nearly a century, it's been known that drugs of abuse alter the immune system. Since the outbreak of the AIDS epidemic in the early 1980s, however, an explosion of data has given rise to a rapidly evolving area of research. Investigators around the world have shown that such psychoactive drugs as heroin, morphine, cocaine, and marijuana affect both the neurophysiologic and immunologic systems. In recent years, researchers have produced strong experimental evidence that these drugs of a
